Patient-reported outcomes have shown independent prognostic value for patients with nonsmall cell lung cancer (NSCLC). However, translating patient-reported outcomes into useful prognostic information for individual patients has been problematic.
A total of 94 patients with advanced NSCLC and an Eastern Cooperative Oncology Group performance status (PS) of 0 to 2 who qualified for chemotherapy rated symptom severity using the M. D. Anderson Symptom Inventory before and after their first chemotherapy cycle. Prognostic values of baseline symptoms and changes in symptom severity were examined by Cox proportional hazards models.
In multivariate analysis, controlled for demographic and other factors, baseline coughing rated > or =4 independently predicted significantly higher risk for shorter survival (hazards ratio [HR], 8.69; P < .0001). Patients with coughing > or =4 and a PS of 2 were more likely to have shorter survival (HR, 20.6; P < .0001) than patients with coughing <4 and a PS of 0 to 1. A 1-point or greater increase in severity of fatigue (P < .05), shortness of breath, or poor appetite (P < .01) from baseline to the end of the first chemotherapy cycle was also found to be independently associated with higher risk for poor survival.
An increased risk for shorter survival was indicated by moderate to severe coughing at baseline or by increased fatigue or shortness of breath during the first chemotherapy cycle in patients with advanced NSCLC. Although cross-validation is needed, these data suggest that an individual patient's symptom severity scores, quickly obtainable in the clinic, might contribute clinically useful information for treatment planning for that patient.

    ABSTRACT: A serotonin transporter gene, SLC6A4, is thought to be related to nicotine dependence and depression, one of the comorbidities of chronic obstructive pulmonary disease (COPD). To investigate the association between SLC6A4 variation and tobacco consumption, susceptibility to COPD, and depression status. In all, 247 patients with COPD and 119 control subjects were genotyped for 5 tag single-nucleotide polymorphisms (SNPs) of SLC6A4. We analyzed the correlation between these genotypes and COPD, using the results of a pulmonary function test or chest computed tomography; data on tobacco consumption (pack-years); and the depression score based on the hospital anxiety and depression scale (HADS) after adjusting for age, gender, and smoking status (and pack-years, when appropriate). The rare allele rs2020936 was significantly associated with COPD incidence in the trend model (P = 0.003; odds ratio, 2.20; 95% confidence interval, 1.31-3.74). This allele was also associated with the number of pack-years (P = 0.026). The major allele of another SNP of SLC6A4, namely rs3794808, correlated with the HADS depression score (P = 0.016). We conclude that SLC6A4 variation affects COPD pathogenesis, and this effect depends partly on tobacco consumption. SLC6A4 variation also affects depressive symptoms. SLC6A4 could be modified to prevent COPD and treat the depressive symptoms of COPD.

    ABSTRACT: We conducted a study to establish the psychometric properties of a module of the M. D. Anderson Symptom Inventory (MDASI) developed specifically for patients with lung cancer (MDASI-LC). The MDASI measures 13 common "core" symptoms of cancer and its treatment. The MDASI-LC includes the 13 core MDASI symptom items and three lung cancer-specific items: coughing, constipation, and sore throat. MDASI-LC items were administered to three cohorts of patients with lung cancer undergoing either chemotherapy or chemoradiotherapy. Known-group validity and criterion (concurrent) validity of the MDASI-LC were evaluated using the Eastern Cooperative Oncology Group performance status and the 12-item Short-Form Health Survey. The internal consistency and test-retest reliability of the module were adequate, with Cronbach coefficient α-values of 0.83 or higher for all module items and subscales. The sensitivity of the MDASI-LC to changes in patient performance status (disease progression) and to continuing cancer treatment (effects of treatment) was established. Cognitive debriefing of a subset of participants provided evidence for content validity and indicated that the MDASI core items and three additional lung cancer-specific items were clear, relevant to patients, and easy to understand; only two patients suggested additional symptom items. As expected, the item "sore throat" was sensitive only for patients receiving chemoradiotherapy. The MDASI-LC is a valid, reliable, and sensitive symptom-assessment instrument whose use can enhance clinical studies of symptom status in patients with lung cancer and epidemiological and prevalence studies of symptom severity across various cancer types.
